At east middle school, there are 58 left-handed students and 609 right-handed students. the numbers of left- and right-handed students at west junior high are proportional to the numbers at east middle school.

Hello there!

in East middle school there are 58 left-handed students and 609 right-handed students.

You could calculate the ratio between them in the next way:

divide the biggest number by the smaller one:

x = 609/58 = 10.5.

then the proportion is 1:10.5 wich means that for every left-handed student, you have 10.5 right-handed students, but the 10.5 looks weird, we could write this ratio as 2:21 by multiplying each side by 2.

and now for every two lefthanded students, there are 21 right-handed students:

now you know that at West Junior High the proportion between left-handed students and right-handed students is proportional to the numbers at East Middle School.

this means that the ratios are equivalent, or:

if there are Y left-handed students at West Junior High, then there are X = 10.5*Y right-handed students in West Junior High.

Where X and Y are not necessarily equal than in East Middle School, just the ratios are proportional between them

answer: 25 is the correct answer

step-by-step explanation:

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
